  • 도시 대기중 오존과 같은 광화학산화물에 의한 오염의 심각성이 최근 더욱 증대되고 있는 가운데 그 원인의 일부가 휘발성 유기화합물(Volatile Organic Compounds : VOCs)의 배출량 증가라는 것이 확인되었고, 더욱이 일부 VOCS의 경우에는 인체에 발암성을 나타내는 등 직접적으로 유해한 것으로 알려져 세계 각 국에서 VOCs의 감소에 많은 관심을 기울이고 있다. 특히 BTEX는 산업공정에서 많이 사용되는 물질로서 반드시 처리되어야 할 규제대상물질이다. (중략)

  • Levels of beauvericin (BEA) and enniatins (ENNs: ENA, ENA1, ENB, and ENB1) were examined in fresh ginger (n = 43) and ginger powder (n = 31) samples from Korea. In the ginger samples, incidence of BEA contamination was highest, at 62.79%, with a maximum detected BEA level of 640.07 ㎍/kg. ENNs in were found in up to 11.63% (ENB, ENB1) of ginger samples, with a maximum detected level of 91.02 ㎍/kg (ENA). In the ginger powders, ENB contamination displayed the highest rate of incidence (70.97%), but the highest level of BEA (1,344.18 ㎍/kg) exceeded that of ENB (413.99 ㎍/kg). The incidences of ENA, ENA1, ENB, and ENB1 presence in ginger powders were 29.03%, 22.58%, 70.97%, and 35.48%, respectively, and their highest detected levels were 220.45, 156.61, 413.99, and 70.29 ㎍/kg, respectively. The incidence of BEA and ENN contamination was higher in ginger powder than in ginger. Respective co-occurrence rates of BEA and ENNs in ginger and ginger powder samples were 16.28% and 64.52%, indicating that the BEA and ENN co-contamination rate was highest in ginger powder as well. This is the first report on the presence and co-occurrence of BEA and ENNs in Korean ginger and ginger powder.

  • Nowadays, smart phone became an important part of communication media and integrated into people's life. If callers rely on helmet-mounted display(HMD) augmented reality technique to add two-way user's facial expression, appearance, actions during the calling process, it will let callers have a visualized fantastic sensual experience. And through that method can break the limitations of vision, so research that technical problem can promote the development of visual arts, that is meaningful. This paper will choose and composite several existed technologies to set up two hypothesis, try to realize AR video calling. Through comparison and analysis to find those two hypothesis' problem, and create design solutions to solve problems. And use case study method to present two cases for prove my paper's result that is those two hypothesis can be realize in future. Use those technologies can bring more convenience and enjoyment to people's life. It can be predicted that AR video calling process can be successfully realized and will have unlimited development in future.

  • Objective: This study presents an observation and analysis on behavioral characteristics of old users in comparison to young users in the use of control on display interface. Background: Touch interface which allows users to control directly on display, is conceived as delight and easy way of human-computer interaction. Due to the advantage in stimulus-response ensemble, the old users, who typically experiencing difficulties in interacting with computer, would expected to have better experience in using computing machines. Method: Twenty nine participants who are over 50 years old and 14 participants who are in 20s years old were participated in this study. Three primary tasks in touch interface, which are tap, move, and flick, were delivered by the users. For the tap task, response time and point of touch response were collected and the response bias was calculated for each trial. For the move task, delivery time and the distance of finger movements were recorded for each trial. For the flick task, task completion time and flicking distance were recorded. Results: From the collected behavioral data, temporal and spatial differences between young and old users behavior were analyzed. The older users showed difficulty in completing move task requiring eye-hand coordination.

  • The choice of eco-friendly materials for ground improvement is a necessary way forward for sustainable development. Adapting naturally available biopolymers will render the process of soil stabilization carbon neutral. An attempt has been made to use β-glucan, a natural biopolymer for the stabilization of lean clay as a sustainable alternative with specific emphasis on comprehending the effect of confining stresses on lean clay through triaxial compression tests. A sequence of laboratory experiments was performed to examine the various physical and mechanical characteristics of β-glucan treated soil (BGTS). Micro-analysis through micrographs were used to understand the strengthening mechanism. Results of the study show that the deviatoric stress of 2% BGTS is 12 times higher than untreated soil (UTS). The micrographs from Scanning Electron Microscopy (SEM) and the results of the Nitrogen-based Brunauer Emmett Teller (N2-BET) analysis confirm the formation of new cementitious fibres and hydrogels within the soil matrix that tends to weld soil particles and reduce the pore spaces leading to an increase in strength. Hydraulic conductivity (HC) and compressibility reduced significantly with the biopolymer content and curing period. Results emphases that β-glucan is an efficient and sustainable alternative to the traditional stabilizers like cement, lime or bitumen.

  • Silicon nanowires (Si NWs)-based top-gate field-effect transistors (FETs) are constructed by using Si NWs transferred onto flexible plastic substrates. Si NWs are obtained from the silicon wafers using photolithography and anisotropic etching process, and transferred onto flexible plastic substrates. To evaluate the electrical performance of the silicon nanowires, we examined the output and transfer characteristics of a top-gate field-effect transistor with a channel composed of a silicon nanowire selected from the nanowires on the plastic substrate. From these FETs, a field-effect mobility and transconductance are evaluated to be $47\;cm^2/Vs$ and 272 nS, respectively.

  • Purpose: The purpose of this study was to investigate the relations among emotional intelligence, interpersonal relationship, and job satisfaction among clinical nurses. Methods: Data were collected from 315 nurses who had worked for more than 6 months at five general hospitals by a self-reported questionnaire. The collected data were analyzed with descriptive statistics, t-test, ANOVA, Scheffe-test, Pearson's correlation, and hierarchial regression using SPSS 18.0 program. Results: The mean score of emotional intelligence was 3.42 and the score of self emotional appraisal was the highest. The mean score of interpersonal relationship was 3.44 and the score of intimacy was the highest. The mean score of job satisfaction was 3.04. Emotional intelligence and interpersonal relationship were positively correlated with the job satisfaction. Hierarchial multiple regression analysis showed that use of emotion was the main factor of affecting job satisfaction, which explained 30.8% of the variance for the nurses' job satisfaction together with intimacy, regulation of emotion, position, and monthly salary. Conclusion: These findings indicated that emotional intelligence and interpersonal relationship, especially use and control of emotion and intimacy contributed to nurses' job satisfaction. It is necessary to develop and implement the program for increasing emotional intelligence and interpersonal relationship for improving job satisfaction.
